98.5 Crank but no start

Recently purchased a 98.5 24v for cheap. Previous owner said it needed an injection pump. After putting a new injection pump and lift pump on it still doesn’t start. Bleed the fuel system till fuel was coming out of all injector lines. Checked for codes and there are no codes. After still not starting tried Starting truck with either(I know it’s not good on them but wanted to see if it would run). It did start and run off of either but immediately died after we stopped spraying either. Checked the oil and found a good amount of diesel in the oil. Does this mean injectors are leaking and we need to replace them?

Have you had the block heater plugged in for at least two hours? (verified it is working)
I am anti big expensive electric pumps, they all fail.
The on-side of block pumps last for about 80K and are much cheaper to replace ( I am on Number three at 270K )
Each to their own, but do verify you have fuel pressure.
